Hi @Ashis_Palai, welcome to the Streamlit Community! :wave:

Streamlit’s Community Cloud platform supports deploying Streamlit apps, not Flask apps. You will be unable to deploy Flask apps. You can solve the problem by deploying a Streamlit app instead or deploying the Flask app on a compatible 3rd party cloud application platform such as Heroku.

@snehankekre Thank you so much, sorry i am new … so silly of me , I will write the code using Streamlit again will deploy.
